Victorum Combi
PrePlumb Primary Connections
Connect the primary connections from the Heat
Pump to the unit as shown below.
The primary flow connection is on the bottom
of the inline heater and is a 3/4” internal thread.
The primary return connection is on the return
block of the preplumbed manifold and is a
22mm compression connection.
Heating System Pipe Connections
Connect the heating zone connections as
shown below. In the Victorum Combi unit the
heating zone valves are pre-installed. The hot
water zone valve is also pre-installed.
All heating zone return pipes should be joined
at the cylinder and return via the common
heating return as shown below.
Pressure relief valve Connection
The 3-bar pressure relief valve is incorporated
on the manifold of the PrePlumb tank. The
termination point of the relief pipe must
discharge in a manner that will give ready
warning of the occurrence of overpressurisation
without causing any nuisance or any dampness
in the dwelling.
The connection is a ½” internal thread.
Heating Expansion Vessel
The PrePlumb unit does not have an expansion vessel incorporated. The installer must ensure the
system is protected from the effects of expansion by installing a suitably sized expansion vessel.
Refer to section ‘Sizing, positioning and pre-charge pressure of the heating system expansion
vessel’ for vessel sizing.
